A couple of points. The population figures are for slightly later, 1869 to be precise. But close enough to be meaningful.

Despite the text claiming that it was boom time for Austrian brewing, the amount of beer produced per head was quite small. Only Salzburg, Niederösterreich and Oberösterreich look impressive. I'll remark that Salzburg, the are producing relatively the most, had been part of Bavaria for a few years during the Napoleonic Wars. Bohemia and Moravia were well behind, which came as a bit of a surprise. As the reputation of Bohemian beer in particular was on the up.

That'll do for now. But I don't think I've quite finished with these numbers yet.
